EMILE M. E. E. THOREY, OF UNION HILIL, NEW JERSEY.

COCK.

SPECIFICATION forming part of Letters Patent No. 261,068, dated July 11,1882.

Application filed February 28, 1882.

To all whom it may concern:

Be it known that I, EMILE M. E. E. THOREY, of Union Hill, in the countyof Hudson and State of New Jersey, have invented a new and ImprovedCook, of which the followingis a full, clear, and exact description.

The object of my invention is to provide a new and improved cock, inwhich the plug fits very closely in the socket.

The invention consists in a cock provided with springs for holding theplug closely in the socket, for preventing gas or liquid from escapingbetween the sides of the plug and the socket,

The invention further consists in turning heads in the top of the plugand in the bottom of the socket, to which heads the tensionspring of theplug is attached, and upon one of which heads the pressure-spring rests.

The invention also consists in a disk contained in a cap on the top ofthe socket, which disk is provided with a handle and with studs passinginto the upper end of the plug, whereby the plug will be turned whenthis disk is turned by means of its handle, all as will be fullydescribed hereinafter.

Reference is to be had to the accompanying drawings, forming part ofthis specification,

.in which similar letters of reference indicate corresponding parts inall the figures.

Figure 1 is a longitudinal sectional elevation of my improved cock onthe line a n, Fig. 2, showing it opened. Fig. 2 is a sectional plan viewof the same on the line x 00, Fig. 1. Fig. 3 is a plan view of the underside of the screwcap of the cock. Fig. at is a sectional'plan view ofthe cap of the cock on the line y 3 Fig. 1. Fig. 5 is a plan view of theupper end of the plug.

The plug A,which is tapered and made hollow, and is provided with theusual opposite apertures, 13, fits into the tapering socket C'.

A head, D, provided with a downwardlyprojectin g stud or book, E, restsloosely to turn in a recess in the top of the plug A, the hook Eprojecting down through the top of the plug.

A spiral spring, F, is attached at its upper end to the hook or stud E,and the lower end of this spring is attached toan upwardly-projectingstud or hook, G, attached to the inner surface of ahead, H, fittingloosely to turn (No model.)

in a (recess in the bottom of the socket or casing A cap, I, is securedover the lower end of the socket O.

A screw-cap, J, is screwed on the upper end of the socket G, and throughthe top of this cap J a spindle, K, passes, provided at its upper endwith a winged handle, L, or other suitable handle, and at its lower end,which is within the cap J, with a disk, M, provided with two or moredownwardly-projecting studs, N, fitting in corresponding apertures, O,in the top of the plug A.

The disk M is provided in the middle of its lower surface with a recess,P, for receiving the upper end of a spiral spring, Q, the lower end ofwhich rests on the head D in the top of the plug A.

A circular projection, R, on the top of the cap J, is provided in itsedge with a quadrant recess, S, into which a stud, T, passes, projectingdownward from the handle L, which stud T strikes against the ends ofthis recess S, and

thus limits the movements of the handle L and the plug A to aquarter-turn.

If desired, the top of the cap J may be provided with a quadrant-groovein place of the quadrant recess S, or with two projections sep aratedthe distance of a quarter-circle. The spindle K is provided at its lowerend with a conical enlargement, K, which fits into-a conical recess inthe lower surface of the cap J, and the spring Q presses the conicalenlargement K into the conical recess in the cap J, and thus prevents anescape of gas or liquid through the space between the lower part of thespindle and the aperture in the cap. I

The operation is as follows By turning the handle L the spindle K andthe disk M will be turned, and as the studs N pass into the apertures Oin the top of the plug A the plug will be turned also. The springF willnot be turned or twisted, as the head D, to which the springF isattached, can turn in the top of the plug A. The plug A is drawndownward into the socket (J by the spring F, and is pressed downward bythe spring Q. The springs F and Q hold the heads D and H closely in theupper end of the plug and the lower end of the socket O, and prevent theescape of gas or liquid between the headsand the sides of the recessesinto which they fit. If, by accident, any liquid or gas should escape atthese heads, it is prevented from leaving the socket C by the caps I andJ.

My improved cock can be used for gases or liquids. Its special advantageis that the plug fits so closely in its socket as to make an escape ofgas or liquid almost impossible and without interfering with the easyworking of the cock.

Having thus fully described myinvention, I claim as new and desire tosecure by Letters Patent- 1. In acoek, the coinbination,with the socketG and the plug A, of the spring F and the turning heads D and H, towhich the ends of the spring are attached, substantially as herein shownand described, and for the purpose set forth.

2. In a cook, the combination, with thesocket O and the plug A, of thecap J and the disk M, provided with a handle, L, and studs N, passinginto the top of the plug, substantially as herein shown and described,and for the purpose set forth.

3. In a cook, the combination, with the socket O and the plug A, of thecap J, the disk M, provided with a handle, L, and studs N, passing intothe top of the plug, and of the spring Q, between the plug and the diskM, substantially as herein shown and described, and for the purpose setforth.

4. In a cock, the combination, with the socket O and plug A, of the diskM, provided with studs N, passing into the plug A, and of the springs Fand Q, substantially as herein shown and described, and for the purposeset forth.

5. In a cock, the combination,with the socket G and plug A, of the diskM, provided with a handle, L, and studs N, passing into the plug, of thesprings F and Q, and the heads D and. H, substantially as herein shownand described, and for the purpose set forth.
